Abstract
Systems and methods are disclosed relating to composite photonic materials used to design structures and detecting material deformation for the purpose of monitoring structural health of physical structures. According to one aspect, a composite structure is provided that includes a base material, an optical diffraction grating and one or more fluorophore materials constructed such that localized perturbations create a measurable change in the structure's diffraction pattern. An inspection device is also provided that is configured to detect perturbations in the composite structure. The inspection device is configured to emit an inspecting radiation into the structure and capture the refracted radiation and measure the change in the diffraction pattern and quantify the perturbation based on the wavelength and the angular information for the diffracted radiation.
